NOCTURIA
Ask the Following Questions:
- Is there daytime frequency of urination also? If there is daytime frequency, the differential diagnosis of polyuria should be considered.
- Is there associated pain or difficulty voiding? These findings would suggest cystitis, prostatitis, and urethritis.
- Is there dyspnea, orthopnea, or peripheral edema? These findings would suggest congestive heart failure. If there is no dyspnea or edema, one should consider chronic nephritis.
DIAGNOSTIC WORKUP
Routine laboratory tests should include a CBC, sedimentation rate, urinalysis, chemistry panel, and urine culture and sensitivity. A quantitative 24-hr urine volume should be determined. If this is above normal, the differential diagnosis of polyuria should be considered and additional workup can be found on

.
Catheterization for residual urine will help determine if there is bladder neck obstruction. If congestive heart failure is suspected, a chest x-ray, EKG, and venous pressure and circulation time should be done. For further evaluation, a nephrologist or urologist may be consulted.
